I also got the email from Expansys asking me to confirm my order or let them allocate it to someone else.

I placed my order when their website had the mistaken $199.99 price. Because I live outside the USA, Expansys wouldn't process my credit card and they asked if I was willing to pay by bank transfer. I replied yes, and immediately received instructions to pay $314.94, including delivery to Trinidad and a $30 "wire-transfer fee". So I paid.

I have replied to Expansys saying I have already paid and asking them to ship asap. I have no idea what will happen next. The Terms and Conditions on Expansys' web site refer only to correcting pricing errors "before payment is processed". My payment is already processed, so maybe I'll be lucky and get a bargain.

Somehow I doubt it.
